Conveying device for powdery and/or granulated material

Abstract

A conveying device for free-flowing fine-particle solids (bulk material), in particular for powdery and/or granular (mixed) material, especially plastic granulate, includes a vertically arranged and flexibly mountable pipe for the conveyance of, preferably, polymer granulates, for example in a plant for the filling of polymer granulates. The transport pipe may be included on a mobile work platform.

What is claimed is: 
     
       1. A conveying device, comprising:
 a conveying pipe, and 
 a pipe inlet flange on an upper conveying pipe end of the conveying pipe, 
 a pipe outlet flange on a lower conveying pipe end of the conveying pipe, 
 a lower rotationally symmetric counter flange coupled to the pipe outlet flange, and 
 rapid-action clamping devices coupled to the pipe inlet flange for use as pipe fastenings, the rapid-action clamping devices being configured to connect to an upper rotationally symmetric counter flange and an upper receiving collar, wherein the rapid-action clamping devices are configured to provide a quick and seal-tight connection of the pipe inlet flange to the upper rotationally symmetric counter flange. 
 
     
     
       2. The conveying device according to  claim 1 , wherein the conveying device is constructed to minimize dead space. 
     
     
       3. The conveying device according to  claim 1 , wherein, on one or both rotationally symmetric counter flanges, sensors are included by which the docking of a pipe end to a docking device or to a counter flange can be reliably detected by virtue of an initiator query. 
     
     
       4. The conveying device according to  claim 1 , wherein the conveying pipe is disposed on a mobile work platform for transport of the conveying pipe to different filling sites on a stage, the mobile work platform containing lifting, transporting and pivoting devices for positioning of the conveying pipe at different docking devices on the stage. 
     
     
       5. The conveying device according to  claim 4 , wherein the lifting, transporting and pivoting devices are supported by electric drives. 
     
     
       6. The conveying device according to  claim 4 , wherein the mobile work platform is movable by electric drives. 
     
     
       7. The conveying device according to  claim 1 , further comprising
 a separate lifting-pivoting device coupled to the conveying pipe and adapted for raising of a floor cover; and 
 a pivoting guard rail coupled to the conveying pipe and adapted to protect a floor opening. 
 
     
     
       8. The conveying device according to  claim 7 , wherein the pivoting guard rail is locked by electromechanical means and is released only by means of a light scanner adapted to identify the floor opening. 
     
     
       9. The conveying device according to  claim 4 , wherein a positioning operation of the mobile work platform is supported by a common position of light spots of positioning lasers supports. 
     
     
       10. The conveying device according to  claim 9 , further comprising at least two positioning lasers adapted to create light spots on a floor, such that a common position of the light spots serves as indicia of appropriate operational positioning of the mobile work platform. 
     
     
       11. The conveying device according to  claim 1 , wherein the conveying pipe is configured to fixedly connect to a floor opening cover. 
     
     
       12. The conveying device according to  claim 1 , wherein the upper and lower rotationally symmetric counter flanges are configured to connect to respective counter flanges of corresponding containers, pipeline ends, or other docking devices. 
     
     
       13. The conveying device according to  claim 1 , wherein each rapid-action clamping device comprises hook and lever elements. 
     
     
       14. The conveying device according to  claim 4 , wherein the mobile work platform is movable by movable drives.
